muw^ I W. &Ho (Meta UNITED STATES PATENT WARREN E. ANDREWS, OFWORMLEYSBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO ALFRED H. SHAFFER,OF HARRISBURG, PENNSYLVANIA.

ANVIL.

To all whom it may concern:

Be it known that I, WARREN E. ANDREws, a citizen of the United States ofAmerica, residing at lVormleysburg, in the county of Cumberland andState of Pennsylvania, have invented certain new and useful Improvementsin Anvils, of which the following is a specification.

This invention relates to new and useful improvements in anvils and moreparticularly to anvils having a removable face plate and horn.

It is an object of the invention to provide a device of this characteremploying a novel manner and method of securing the face plate and hornto the body of the anvil.

It is also an object of the invention to provide a novel device of thischaracter which will possess advantages in points of simplicity,efficieney and durability, proving at the same time comparativelyinexpensive to manufacture.

With the foregoing and other objects in view, the invention consists inthe details of Construction and in the arrangement and oombination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, in which-Figure 1, is a perspective view of an anvil embodying my invention,showing the face plate thereof detached; Fig. 2, is an enlarged sideview of a portion of the anvil partly in elevation and partly in sectionshowing the parts assembled; and Fig. 3, is a side view of the horn.

In the drawings 1, denotes the body of the anvil which may be of theusual or any well known construction and is provided with a removablehorn 2, said horn having a reduced screw-threaded portion 3, formingwith the horn proper, a shoulder 4. The screw-threaded portion 3, isadapted to engage screw threads on the inner surface of thecorresponding bore 5, in the body of the anvil for causing the horn tofit tightly against said body.

The removable face or working plate 6, is provided on its under sidewith a dove-tail tongue 7, eXtending the full length thereof whichengages a dove-tail groove 8, in the top of the anvil body. hen the faceplate Specification of Letters Patent.

{ is at the limit of its movement in the groove 8, it abuts a shoulder9, formed by the projecting edge of the horn, when said horn is Securedto the body. The groove in the body is preferably made slightly narrowerthan the tongue on the face plate, preferably about 1/32 of an inchnarrower, as will be hereinafter more fully set forth. In securing theface plate to the body, the said body is first heated to a dark cherryred, which 'will cause the same to eXpand. The tongue of the face isthen forced into the groove 8, after which the anvil is immersed inwater or other cooling agent. In cooling, the body of the anvilcontracts and the groove being slightly smaller than the tongue, theface adheres closely to the body making it practically one solid piece.In order to remove the face for repairing or renewing the same, theanvil is again heated to a cherry red, and the body of the anvil willeXpand more and the face can then be removed by sliding the same out ofthe groove. In connection with the foregoing, it is proper to state thatthe face plate and horn may be made of fine grade steel and the body ol'some cast material of much cheaper quality. It will thus be seen thatwhen the face or horn of the anvil becomes damaged by wear instead ofgoing to the eX- pense of getting a whole new anvil or having the samerepaired with great difficulty, the face or horn can be removed anddressed or replaced at a very nominal cost.

It is to be understood that I do not wish to coninc myself to theeXactness of the disclosure but may make suitable alterations andchanges therein as fall within the scope of my invention, as set forthin the appended claim.

I claim- An anvil comprising a body having a groove in its top eXtendingthe entire length thereof, a face plate provided with a tongue extendingthe entire length of its under surface received within said groove, anda horn Secured to said body, part of said horn projecting thereabove toform a shoulder against which said plate abuts.

In testimony whereof I affix my signature in the presence of twowitnesses this 25th day of May, 1908.
